Well, we gotta add that we don't mind paying for entertainment - like demolition derby, or a rodeo.
But kinda think not when paying admission so some dealer can try to sell me something. That's why the dealers bring RV's, to sell RV's. Lots of tire-kickers show up, but that happens at the home RV lot too. So, I'd bet any dealer charged a fee to visit the dealer lot, would not have many visitors.
A top nitch salesman can often sell to a tire-kicker. Not all but certainly some. That's his job, sell an RV to a customer, whether he/she want it or not.
If you want to sell us something, don't charge me to see it. JMHO -
The internet is free, that where we search for what we like. THEN, go to see that at the seller lot. And above, right, the RV's show become like concessionairs, the dealers pay a fee to be there, the customers pay a fee to get in, and for parking ... the venue wins the bucks.
